Strange surnames in your family tree

[capocannoniere]

Vanz, Fracasso, Bolson, Bonferai, Sponga, Regamondo, Grisa and Tronco are the funniest-sounding ones.

[Beraud]

One of my Alsacian ancestors' name was Vogeleisen, from High German Vogel ("bird") + Eisen ("iron").
I can't quite make sense out of this name.

Well birds seem to conceptualize transcendence (reaching to the heavens), but yet with a sense of also being delicate and flying from any hint of danger. If one wanted to convey the transcendent nature without the connotation of being delicate and fleeting, it seems they would add something like the word "iron" . Cool name.

"Transcendent resilience"

Or a bird that cannot fly, but the first makes more sense. Unless there is some ancestral story of captivity that would immediately apply at the time of the surname's creation of course.

Are there sandstorms in Poland?

Because one of my peasant surnames is "Kurzawa", which some translate to "sandstorm", but others translate to "swirling cloud of dust", which does sound more literal yet even less expository. I just don't see sandstorms in Poland lol. But I would really like to hear another's impression.
